【摘要】 利用国产GPS定时型接收机,按照国际共视规程,陕西天文台建立了GPS共视法时间比对.研究了影响比对精度的因素,实现了微机控制的数据自动采集和处理,实现了国际间的全面共视比对.1991年3月起,BIPM已正式用于国际原子时TAI的计算中。更多还原

【Abstract】 Using a GPS timing receiver made in China, CSAO have built a GPS common—view time comparing system according to the international common—view regulation. We have established a computer—controlled automatic data collecting and processing system,Done reseaches for many facts which affect the comparing accuracy, and realized international common—view comparision. Since the beginning of 1991, BIPM have been using our comparing results for the computation of TAI.更多还原
